Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 3 generators on 28 points:

(2,4)(6,9,10,11)(13,14,17,22,18,20,16,21)(15,19,24,26,25,27,23,28);(1,2,3,4)(13,15)(14,19)(16,23)(17,24)(18,25)(20,27)(21,28)(22,26);(5,6)(7,11)(8,10)(9,12)(14,20)(15,23)(16,17)(19,26)(24,25)(27,28)

Polycyclic presentation:
